literally, everywhere! Just gotta pick the right times - 70% knowledge, 30% luck!
South Oz - great. All year. Vic, NSW - also great with tons of spots, but crowded. QLD, same. Best around hurricane season (Jul - Sept.) if you like it big, or just after. Too many spots to mention, but I suggest, if you have time and a vehicle, get around & talk to folks - ignore the "localism" bullshh$#@ if you come across it & you can find some uncrowded gems just by looking at a coastal map & reading the weather charts.
